9 / 66 page  DS-0027 Feb 06 External—Free Release Page 9 of 66 OXCF950 rev B DATA SHEET OXFORD SEMICONDUCTOR, INC. the transmitter will complete the current character and enter the idle mode until the CTS# pin is reasserted. Note: flow control characters are transmitted regardless of the state of the CTS# pin. 28 (E5) I DSR# Rx_Clk_In Active-low modem data-set-ready input. If automated DSR# flow control is enabled, upon de-assertion of the DSR# pin, the transmitter will complete the current character and enter the idle mode until the DSR# pin is reasserted. Note: flow control characters are transmitted regardless of the state of the DSR# pin External receiver clock for isochronous applications. The Rx_Clk_In is selected when register CKS[1:0] = ’01’ 30 (D5) I RI# Tx_Clk_In Active-low modem Ring-indicator input External transmitter clock. This clock can be used by the transmitter (and indirectly by the receiver) when register CKS[6] = ‘1’. 21 (F4) O XTLO Crystal oscillator output 20 (H4) I XTLI Crystal oscillator input or external clock pin. Frequency 1.8MHz -> 60MHz. For 1.8 to 20 MHz, a crystal may be used. Above this range, an external clock source is required. 34 (C6) O O I LBCS# OUT1# A[5] Local Bus Mode : Active low local bus Chip select C950 Mode: Active low OUT1 Normal Mode : Address bit 5 35 (C4) O O I LBRD#2 RXRDY# A[6] Local Bus Mode : Active-low local bus read enable C950 Mode:Active low RXRDY Normal Mode : Address bit 6 36 (B6) O O I LBWR# TXRDY# A[7] Local Bus Mode : Active-low local bus write enable C950 Mode:Active low TXRDY Normal Mode : Address bit 7 33 (E4) O O I LBRST2 OUT2# A[4] Local Bus Mode : Active high local bus Reset C950 Mode:Active low OUT2 Normal Mode : Address bit 4 EEPROM 13 (H1) O EE_CK EEPROM clock. In normal operation the frequency of this is XTLI input clock / 64. The clock is only active during configuration following reset. 14 (G2) O EE_CS EEPROM active-high Chip Select. 16 (G3) I EE_DI EEPROM data in. This pin should be pulled up using 1-10k resistor if an EEPROM is used, or pulled up/down depending upon required stand-alone mode.. 15 (H2) O EE_DO EEPROM data out. Miscellaneous Pins 18, 31 (G4, D6) I/O MIO[1:0] User defined IO pins. Note: that if enabled, MIO[1:0] can be used as an interrupt inputs. 17 (H3) I MODE Local Bus mode select. Note Local Bus mode requires indirect addressing, which is only supported by the PCMCIA specification ‘0’ = Normal Mode (CF/PCMCIA compatible) ‘1’ = Local Bus Mode (PCMCIA compatible) Power and Ground2 39, 19, 8 (A5, E3, D3) G GND Ground (0 Volts). The GND pins should be tied to ground |
